    • Abstract

       

      The constitution of Gossypitrin has been established as the 7-glucoside of the flavonol Gossypetin by complete methylation of the glucoside through the acetyl derivative and the isolation of 7-hydroxy-3: 5∶8∶3′∶4′-pentamethoxyflavone by the hydrolysis of the above methylated glucoside. The acetyl derivative of the pentamethyl gossypetin has also been prepared.

      Our thanks are due to Dr. S. Rangaswami for help in connection with the microanalysis of the compounds.
